FILE DOCUMENT

This document explains the contents of data files stored in the METIS
repository of the Finnish Meteorological Institute, supporting the
study "Projections of deep and near-surface layer soil moisture for
Europe: long-term mean changes and occurrence of severe droughts" by
Kimmo Ruosteenoja and Heikki Tuomenvirta, submitted to "International
Journal of Climatology".

In the file names, mrsos refers to the near-surface (0-10 cm) and
mrso_60-100 to deep soil (60-100 cm) moisture.


(a) Soil layers in models

Text file: soil_layers_in_models.dat

This file shows the upper and lower ends of the 3-20 soil layers for
which soil moisture (variable "mrsol") is given in the various
models. The ordinal number of the layer is given first, followed be
the upper and lower ends of the layer in metres.  The layers are
depicted in Fig. 1 of the study.


(b) Spatial mean values of temperature, precipitation and soil
    moisture in individual models

Text file: long-term_spatial_means_4_variables_ssp245.dat

This file shows spatial mean values of four variables, temperature (in
K), precipitation (mm/day), and near-surface (0-10 cm) and deep-soil
(60-100 cm) moisture (both in kg/m2), averaged over four 30-year
periods: 1981-2010, 2020-2049, 2040-2069 and 2070-2099.  Mean values
are provided for (i) six sub-regions (N-EUR, BRIT, W-EUR. E-EUR,
SW-EUR, SE-EUR; see Fig. 3), (ii) 12 calendar months (1=January,
... 12=December) and up to 4 parallel runs per model. Projections are
given for the SSP2-4.5 scenario. If the data are missing from some
variable, model or parallel run, a code of missing value (-9999) is
used.


(c) Spatial mean changes in soil moisture

-Multimodel mean and median changes (in %) relative to 1981-2010

-Scenarios: SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5 (separate files)

-30-year running means from the period 1935-64 to 2071-2100. In
 the files, the time is the mid-point year of the 30-year period.

-Spatial averages for ten subregions:
 x=1: Entire Finland,  x=2: Northern Finland,  x=3: Southern Finland,
 x=4: Northern Europe,
 x=5: British Isles,  x=6: Western Europe,  x=7: Eastern Europe,
 x=8: South-Western Europe,  x=9: South-Eastern Europe,
 x=10: Entire European continent

-z variable refers to the monthly, seasonal and annual means:
 z=1-12 - calendar months;
 z=13 - Dec-Feb; z=14 - Mar-May; z=15 - Jun-Aug; z=16 - Sep-Nov;
 z=17 - Annual mean

(d) Percentage changes in soil moisture; geographical distributions

-Multimodel mean and median changes (in %) relative to 1981-2010

-30-year running means from the period 1950-79 to 2071-2100. In
 the files, the time is the mid-point year of the 30-year period.

-Scenario: SSP2-4.5

-Spatial resolution: 0.25 x 0.25 degrees; 9-point spatial smoothing

-z variable refers to the monthly, seasonal and annual means:
 z=1-12 - calendar months;
 z=13 - Dec-Feb; z=14 - Mar-May; z=15 - Jun-Aug; z=16 - Sep-Nov;
 z=17 - Annual mean

(e) Probabilities for low soil moistures; multimodel medians

-Scenarios: SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5 (separate files)

-Probabilities (in %) for the Jun-Nov soil moisture being lower than
 the absolute minimum or the 1th, 2th, 5th or 10th percentile in
 1950-1999; spatial means for six subregions and three scenario
 periods; multi-model medians.

-Both variables (mrsos and mrso_60-100) included.
